HUB-LINER.

Application filed July 24, 1916.

T 0 all whom it may concern Be it known that I, WILLIAM F. BAU- MEYER, acitizen of the United States, residing at Sparta, in the county ofRandolph and State of Illinois, have invented certain new and usefulImprovements in I-Iub- Liners; and I do declare the following to be afull, clear, invention, such as will enable others skilled in the art towhich it appertains to makeand use the same.

This invention relates to improvements in wear plates for locomotivewheels, particularly that'character of the device commonly known as ahub liner.

It is well known to those skilled in the art that modern locomotives areprovided with very long rigid wheel bases, and therefore it is necessaryto allow a considerable amount of lateral play between the wheel hubsand the journal boxes in order to prevent binding of these parts whenthe engine passes over curves. "The lateral thrust of the wheels againstthe journal boxes causes the parts to wear away very rapidly until in ashort time the operation of the locomotive becomes dangerous.

It is the object of my invention to reduce the friction between the endsof the wheel hubs and the journal boxes by the provision of hub linersof simple and improved construction.

While there are many hub liners for this purpose on the market, nonehave proven satisfactory for the reason that it has been found diflicultto hold the sections together when they are made in more than one part,and to apply them when formed of a single )late. I l A hub linerconstructed in accordance with my invention may be quickly appliedwithout dropping the wheels or otherwise removing parts of thelocomotive.

With this general object in View, my invention resides in the novelfeatures of construction, combination, and arrangement of parts whichwill be hereinafter more particularly described and claimed and shown inthe drawing wherein:

Figure 1 is a side elevation of my improved hub liner detached- Fig. 2is a vertical section taken approximately on the plane of the line 22 ofFig. 1; Fig. 3 is an enlarged detail vertical section taken on the planeof the line 33 of Fig. 2; and Fig. 4

and exact description of the- Patented Dec. 12, 1916. Serial No.111,085.

is a similar view 4% of Fig. 1.

Referring more particularly to the drawing in which similar referencecharacters indicate like parts, the numeral 1 designates a portion of alocomotive whee] fixed to the shaft 2 around which my improved hub liner8 is disposed. This liner it will be seen consists of a circular plateformed of two sections 4 and 5, each of which is semicircular, theabutting edges being straight and preferably coinciding with a. planepass ing through the center of said plate.

The plate is provided with a central circular opening 6 for thereception of the axle 2. The portion or section 4 of the plate has alongiti'idinally extending tongue 7 formed on its straight edge fordisposition in a similarly extending groove 8 formed in the straightedge of the section 5. This arrangement holds the two parts of the platetogether against lateral shifting relative to each other, and yetpermits the plate to be readily applied about the axle without removingthe wheel 1.

The plate is further provided with a circumferentially extendingsemi-circular groove 9 in its periphery in which the elements used forretaining the two parts of the plate together are disposed. Atdiametrically opposite points on the periphery of the plate and in thebottom of the groove 9 is formed a pair of sockets 10. It will be notedthat the sockets of each pair are disposed a slight distance apart andthat the plane passing through each pair is substantially at rightangles to the plane of the straight edges of the sections of the plate.In other words the sockets in each portion of the plate 3 are formed inthe cen ter of the grooved portion thereof.

In the groove 9 is disposed a pair of semicircular spring metal rods 11which have their free ends bent inwardly toward each other to providelugs 12, the latter being disposed in the sockets 10-when the rods arein operative position. The resiliency of the rods which are preferablyformed of rather heavy spring metal, causes their ends to spring towardeach other when they are removed from the plate, thus when they are inoperative position they; will tightly grip on the periphery thereof andhold thevsections immovable.

It is obvious that in the use of this hub on the plane of the line linerthat the two parts are separated and disposed around the axle 2 betweenthe Wheel 1 and the adjacent journal box Without removing said Wheel,whereupon the spring metal rods 11 are disposed around and in theperipheral groove of the plate and the lugs forced into the sockets 10.Any thickness of plate may be used, depending upon the amount which theparts of the Wheel in the journal box have been worn, but in all cases,the means for holding the two sections together will be the same.

WVhen removing a plate for any purpose such as to place a thicker platein position, the rods 11 must first be removed. In order to facilitatethis removal one or more notches 13 are formed in either or both sections 4: and 5 at the periphery thereof. In the present case I haveillustrated these notches as two in number and disposed in the portion 4adjacent the sockets 10. These notches are so formed that a suitablehooked tool may be caught beneath one of the ends of each rod 9 in orderto force the adjacent lug out of its socket.

As hereinbefo're mentioned, plates of various thicknesses may be usedand it is also contemplated using the same in various sizes and shapes.Such a. device as this may also be used on machines or vehicles otherthan locomotives without departing from the spirit of the invention.

I claim:

A hub liner of the class described comprising a circular plate formed oftwo semicircular sections, the periphery of saidplate having acircumferentially extending groove therein, each section of said platehaving a pair of sockets formed substantially at diametrically oppositepoints in the bottom.

of said circumferential groove, said sockets being disposed in planes atright angles to the line of divisionof said plate, a pair ofsubstantially semi-circular spring metal bands removably disposed insaid circum ferential groove and adapted to hold the two sectionstogether, the resiliency of said bands causing the ends thereof to movetoward each other to tightly grip said plate, and inwardly extendinglugs formed on the free ends of each of said bands and at right anglesthereto, said lugs being disposed in the aforesaid sockets.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
